Abstract

The method involves fixing a pipe section in a matrix (9), opening out a pipe end (6) of the pipe section using a form bolt under the formation or removal of a profile of the pipe section. The form bolt has a layer (20) with a polygonal cross-section and another layer (21) with a round cross-section. An expanding device (23) is attached on the pipe end. The open-out pipe end is stretched in an axial direction during an expansion process. An independent claim is also included for a device for executing a method for producing pipe connections.
